Why is Letters from Iwo Jima such a BS movie? I hate Japs?

It's a joke. They have Nishi "befriending" the American. That's complete bullshit. Why don't they show what they did to Ralph Ignatowski? (drag him into a tunnel, bayonet him, cut off his tongue, eyes, ears, and break both arms and both legs oh and they cut off his genitals and shoved them into his mouth before smashing in his head) They did this for 3 days...cowards can't even fight above ground. Oh yeah and ralph was 18.
